ELECTRICAL CONTACTOR.

Application filed December 1, 1920. Serial No. 427,640.

To. all whom it may concern:

Be it known that I, GEORGE L. SMITH, a citizen of the United States of America, and resident of Fort Wayne, in the county of Allen'and State of Indiana, have invented certain new and useful Improvements in Electrical Contactors, of which the following is a specification.

This invention relates to improvements in electrical cont-actors of that type ada ted for controlling electrical apparatus in w ich numerous electrical circuits are intermitchimes. I for closing the circuits of the various elec trical chime members of a group of chimes of usual construction, selectively at predetermined periods and in successive order so as to affect a melody in the operation of the chimes. The object of the invention is to provide apparatus for making and breaking a series of electrical circuits selectively in predetermined chronological order and metre.

The object of the invention is accom plished by the construction illustrated in the accompanying drawings in which:

Fig. 1 is a side elevation of the apparatus, there being parts broken away;

Fig. 2 is an end elevation of Fig. 1, parts thereof being shown broken away and in section; and

Fig. 3 is a detail view showing disengaged relation of thecontacting member and rota.

Similar characters of reference indicate correspondin parts throughout the several views and re erring now to the same:

1. Is a base upon which is mounted a frame 2 in which is supported a gear mechanism consisting of a train of gears 3,incl1 1ding a governor 4 for regulating the velocity of the gear mechanism. Also a sprocketwheel 5 is provided by means of which movement is imparted to the train of gears, the wheel-being adapted for connection with a weighted chain (not shown) for driving the same.

In connection with the gear mechanism is arranged to be driven thereby a pin-wheel 6, and also a rota 7, the former being connected with the gear mechanism so as to rotate at a greater velocity than that of the rota. An oscillating member is mounted upon a shaft 8 and comprises a base 9 composed of insulating material upon which are fixed a pair of posts 10, the upper ends of which support a metallic bar 11. The

posts also support a cross-bar 12 of insu- 4 has a'crank 14 fixed upon one of its ends, which has connection with a pawl 15 pivotedon the frame 2 of the gear mechanism by means of a connecting bar 16 by which movement is'imparted to the oscillating member as the pawl is engaged and moved successively by the pins 6' on the pin-wheel. Upon the insulated base 9 are secured a series of tongues 17 suitably spaced apart, and each having a terminal bolt '18 by which it is secured to the base at one of its ends. Each tongue has at its oppositeend a contact pad 19 and the metallic bar 11 base. series of contact pads 20 corresponding in number and arrangement with the pads 19 on the springs adapted to form electrical contact respectively therewith. In the cross bar 12are loosely mounted a series of jacks 21 that extend osely through the corresponding tongues 17 and each has a shoulder 22 thereon that engages the corresponding tongues 17 so as to limit its movement relative to the oscillating member.

The rota 7 is mounted upon an axle 23 that is actuated by the gear mechanism, and has an outer shell 24 supported upon an insulating stratum 25, and upon the outer shell are a multiple series of projecting studs 26 arranged respectively in vertical planes corresponding with the jacks 21 mounted in the oscillating member. The studs 26 of each series are so spaced upon the rota that the corresponding jack on the oscillating member will contact therewith as the oscillating member is actuated and cause the tongue engaged thereby to form electrical contact with the bar 11.

In using the invention the several units A of the electrical chimes are arranged respectively with one terminal in connection with the corresponding terminal bolts 18 of the tongues 17 and the metallic bar 11 and the opposite terminals of the chime circuits are connected respectively to the opposite terminals of an electrical battery B so that as the tongues form contacts with the metallic bar 11 the corresponding chime circuits will be closed and the chimes functioned accordingly- The studs 26 of each series on the rota obstruct the corresponding tongues 17 so that electrical connections are formed between the tongues and the metallic bar 11, thus the corresponding electrical circuits are closed. As the pins 6 become disengaged from the pawl the osciliating member swings outwardly and the tongues 17 are then out of contact with the metallic bar 11 and the electrical circuits are therefore open.

What I claim is:

1. In a controlling device for a series of chime members having a corresponding series of electrical circuits for their operation, a gear mechanism; a rota actuated by said mechanism and having a multiple series of studs thereon; an oscillating member actuated by said mechanism and having a series of tongues thereon corresponding with the multiple series of studs on the rota; a contact member on the oscillating member adapted to form electrical connection with each of the tongues; and a series of jacks arranged respectively to be engaged and actuated by the studs of the corresponding series thereof and to move the respec' tive tongues into contacting positions accordingly.

2. In apparatus of the class described, a rota having a multiple series of projecting studs; an oscillating member having an electrical bar; a series of contact tongues having insulated support on the oscillating member and each being adapted to form contact with the bar; a series of jacks adapted respectively to engage the studs of the corresponding series thereof as the oscillating member is actuated and press the corresponding tongues into contact with the'bar; and mechanism impart-ing movement to the oscillating member and rota. I

3. In apparatus of the class described, a studded rota; an oscillating member having a contact bar; contacting members having linsulated support on the oscillating member including means for engagement with the studs on the rota for pressing the respective members into contact with the bar; and mechanism for actuating the oscillating member and rota.

In testimony whereof I affix my signature, in presence of two witnesses.
